A signal transmission device, an electronic device, a method for reversibly connecting an electronic device, and a method for changing different devices are proposed, in which, in particular, a conducted (e.g., wired) loudspeaker, especially a piezo loudspeaker (2), which is attached to the eardrum (3) and excites it to vibrate, is used, wherein the ear canal (4) generally remains open and the natural acoustic transparency of the outer ear is maintained, since the signal transmission from the electronic device to the loudspeaker and the necessary otoplastic measures are generally placed at least partially outside the ear canal (4).

Disclosed herein, among other things, are systems and methods for sound pressure level measurement for hearing devices. Various aspects include a method for sound pressure level measurement using self-mixing interferometry. The method includes directing a coherent light signal towards an eardrum of a user using an optical generation device, directing an audio signal towards the eardrum of the user using an audio generation device, and sensing a reflected light signal from the eardrum of the user using an optical sensor device. Displacement of the eardrum caused by the audio signal is computed using the reflected light signal, and real ear sound pressure level (SPL) at the eardrum is computed based on the displacement of the eardrum.

The present disclosure relates to an acoustic processing device that can suppress the occurrence of excessive atmospheric pressure changes in the eardrums of a user. Provided is an acoustic processing device comprising: a driver unit having a diaphragm; and a housing in which the driver unit is housed. The diaphragm has a vent hole that communicates a first space on a first surface side of the driver unit in the housing and a second space on a second surface side on the reverse side of the first surface. The present disclosure can be applied to, for example, an earphone device.

An apparatus for detecting ear structure movements or changes, or changes in pressure in the ear-canal of a user, in order to control or affect the function of an associated device. The apparatus includes a sensor apparatus capable of being worn by the user to be located in or adjacent an ear-canal of the user. The sensor apparatus includes at least one sensor being located and configured to detect and capture sensor data relating to middle ear, ear-drum complex, ear-drum margin, and / or other ear structure movements or changes of characteristics, or changes in pressure in the ear-canal of the user. A device is provided for processing and analysing sensor data from the sensor apparatus. The device analyses sensor data concerning: eye movement or directional auditory attention or focus data, and / or voluntary control data.

A diagnostic device is configured to capture diagnostic information about a subject (e.g., the subject's ears). The diagnostic device may include a diagnostic extension housing diagnostic elements (e.g., imaging chip, light sources, or lenses) and an ear canal engagement section coupled to the diagnostic extension. The ear canal engagement section may be shaped to position the diagnostic extension superiorly within the ear canal. For example, one side of the ear canal engagement section may be longer than another, which may enable the ear canal engagement section to contact the inferior wall of the ear canal for a longer distance than it contacts the superior wall. This configuration may allow more movement of the diagnostic extension when the device is inserted into the ear, which further improves the alignment of diagnostic elements with a desired area of the car for diagnoses (e.g., the eardrum).

An ear-wearable electronic device comprises a housing configured for deployment at least partially within an ear canal of a wearer, sound processing circuitry, and a vibratory transducer disposed in the housing and coupled to the sound processing circuitry. The vibratory transducer comprises an oscillator arrangement disposed in a sealed case. The vibratory transducer is configured to generate output signals in the form of audible sound transmissible via air conduction to an eardrum of the wearer and vibratory signals for stimulating a cochlea of the wearer via transcranial bone conduction.

The application relates to an in-ear type sign detection device and system, wherein the in-ear type sign detection device comprises an infrared temperature measurement assembly and a first mounting piece; the infrared temperature measurement assembly is mounted on one end of the first mounting piece close to an eardrum, and the first mounting piece is elastic; when the sign detection device is worn, the first mounting piece is in an external auditory canal of a wearer, and the first mounting piece is deformed elastically so that the infrared temperature measurement assembly is aligned with the eardrum of the wearer, and the infrared temperature measurement assembly is used for detecting the eardrum temperature of the wearer. The first mounting piece can adapt to different external auditory canal shapes, and then the wearer can adjust the in-ear angle of the first mounting piece, so that the infrared temperature measurement assembly can be aligned with the eardrum of the wearer. The problem that existing in-ear type temperature detection devices cannot accurately monitor the core temperature of the human body in some cases due to the fact that the individual differences of the external auditory canal shapes among different users are not considered is solved.
